This is the kind of fasting that I want;
Free those who are wrongly imprisoned;
    lighten the burdens of those who work for you.
Let the oppressed go free,
    and remove the chains that bind people.
Share your food with the hungry,
    and give shelter to the homeless.
Give clothes to those who need them,
    and do not turn your backs to your family and friends.

Isaiah 58:6-7
